Hubbell-Bell 5320-0 Single Gang Box
The Hubbell-Bell 5320-0 is a single-gang, 3-1/2-inch weatherproof box designed for rugged outdoor or wet locations. It features a state-of-the-art powder coat finish for maximum weatherability and scratch resistance, a rugged die-cast aluminum construction, and internal hub threads that comply with NEMA requirements to accept threaded fittings and conduit. Best for outdoor outlets, lighting controls, or devices exposed to the elements. Choose this for durability in harsh environments and when weatherproof seals are essential.
Best for: exterior walls, workshops, or any installation requiring reliable weather resistance. Better for environments where metal boxes must resist corrosion and maintain a clean finish over time. Avoid this if you need a plastic, non-metallic enclosure for a simple indoor install, as metal boxes can require more careful sealing in some interiors.
Newhouse Hardware 1-Gang PVC Old Work Box
This 1-gang PVC old-work box is designed for remodeling projects. It supports non-metallic sheathed cable and can function as a junction box, switch box, GFCI box, or duplex receptacle box. It is ideal for home improvement where a lightweight, corrosion-resistant plastic enclosure is preferred and where retrofits require quick, clean installation.
Best for: home remodels, DIY electrical upgrades, and light commercial improvements where plastic boxes simplify retrofits. Better for interior walls with non-metallic wiring. Note: plastic boxes may require different screws and mounting considerations compared to metal boxes in some installations.
SmarToggle Single Gang Retrofit Box
The SmarToggle retrofit wall box provides stud or no-stud mounting for flexible installations. It uses snap-in 1-1/2″ toggles for a secure, flush fit and includes four wiring ports for simple, organized wiring. This is a strong choice for upgrading existing walls to smart devices or additional outlets without structural changes.
Best for: remodels and smart-home device installations where wall space is limited or where stud framing is variable. Better for projects needing straightforward, reliable mounting in mixed wall types. Consider: ensure the box depth accommodates the device being installed to avoid crush or misalignment.
Southwire MSB1G One Gang Device Box
This single-gang device box from Southwire is depth-adjustable and designed for both horizontal and vertical installations. It includes removable interior mounting blocks to increase cubic inch capacity and ½” knockouts compatible with blue tube or PVC conduit. It’s suitable for flexible cable management and clean installations in media centers or living spaces with diverse wiring needs.
Best for: high-configuration installations where space management and adaptable mounting are important. Better for bottom- or top-ported devices. Avoid this if you only need a minimal, fixed-depth box for simple outlets, as depth adjustment adds complexity to the install.
Southwire MSBMMT5G 5-Gang Box
The MSBMMT5G is a five-gang, depth-adjustable device box designed for heavy-duty and flexible configurations. It features removable mounting blocks to expand cubic inch capacity and ½” knockouts compatible with common conduit systems. This box is well-suited to multi-device installations in home theaters or control panels.
Best for: large-scale or multi-device installations where space and organization are paramount. Better for controlled environments with planned cable routing. Avoid this if a small, single-gang or shallow box is all that the project requires, as the larger footprint may be unnecessary and harder to fit in tight spaces.
Southwire MSB4G Four-Gang Device Box
The MSB4G is a four-gang device box with depth adjustment. Built from thick-wall molded PVC, it offers rigidity and durability for residential and light commercial installs. Top and bottom clamps secure wire entry, and the box supports mounting on wood or metal studs. This box suits projects that require multiple devices in a single location, with robust wire management.
Best for: bundled outlets or switches in media rooms, kitchens, or utility areas where multiple connections are needed. Better for retrofits that demand reliable structural support. Consider: ensure compatibility with the total device count and wire gauge to avoid crowding inside the box.
OneBoxForAll Old Work BaseBox
The OneBoxForAll Old Work BaseBox is an expandable double-gang PVC box designed for versatility. It features an expandable design via an old-work expansion ring, allowing it to adapt to varying gang sizes. It offers a deep 3.5-inch depth and 32 cubic inches of capacity, providing ample space for wire management and standard devices.
Best for: projects requiring future-proofing or field customization where the wall box must adapt to changing device counts. Better for renovations and variable layouts. Avoid this if you only need a fixed single-gang box, as expansion options add complexity and cost.
Buying Guide: Key Considerations For Stand Up Gang Boxes
- Box Type And Use Case: Choose weatherproof metal for outdoors or damp interiors, plastic for quick remodels, and retrofit boxes for stud/no-stud walls.
- Depth And Capacity: Consider cubic inches and depth to fit all conductors, devices, and connectors without crowding.
- Mounting Versatility: Look for boxes with adjustable mounting blocks, removable tabs, or expandable configurations for future upgrades.
- Conduit And Knockouts: Ensure knockout sizes and conduit compatibility match your wiring plan (blue tube, PVC, etc.).
- Device Compatibility: Verify that the box accommodates the number and type of devices (switches, GFCI, outlets) you plan to install.
- Installation Environment: Indoor renovations may favor plastic, while exterior or workshop settings often benefit from metal or weatherproof PVC.
- Code Considerations: Ensure the chosen box complies with local electrical code requirements for location, weatherproofing, and supported conduit fittings.
Frequently Asked Questions
What is the difference between old-work and new-work boxes?
Old-work boxes are designed to install after walls are in place, typically using an expansion ring or mounting clamps. New-work boxes are intended for installation while walls are being built.
When should I choose a weatherproof box?
Weatherproof boxes are ideal for outdoor or damp environments to protect wiring and devices from moisture and corrosion.
How many devices can a multi-gang box support?
That depends on cubic inch capacity and the size of the devices. Always check the box’s listed capacity and plan wire routing accordingly.
Do I need a metal or plastic box?
Choose based on environment, durability needs, and ease of installation. Metal boxes offer durability and grounding, while plastic boxes resist corrosion and are lighter.
Can I retrofit a single-gang box to a multi-gang box?
Some boxes are expandable or designed for retrofits; confirm compatibility with wall type and device count before upgrading.
